Best Answer

Aerogel is the best insulator [.004 W /( MK)] and diamond or diamond-chickenwire-tube (carbon nanotubes) are the best [2320 W/(MK)].

Why does humans conduct electricity?

humans conduct electricity because your body is made 70% of water. so its the best conductor.


Are scissors conductors or insulators?

Depends on what they're made of, not what they are.Anything made of a conducting material is a conductor, whatever it is.Anything made of an insulating material is an insulator, whatever it is.Material properties - conducting or insulating - is more important than shape.Scissors are generally - but not always - made of metal.And metals are usually conductors, making the scissors conductors.But a scissor might have plastic handles. Plastic is usually an insulator, which would make the handles insulators.


What type of metal will conduct electricity the best?

Silver has the highest electrical conductivity of any metal, followed closely by copper, gold, and aluminum.It should be noted that electrical conductivity is a function of temperature and all comparisons must be made at a standard temperature or adjusted for temperature.Answer:The name of the metals are on the left and the conductivity level on the right...[units appear to be 1/(ohm-m)]Aluminum 59Brass 28Cadmium 19Chromium 55Cobalt 16.3Constantin 3.24Copper:Hard drawn 89.5Annealed 100Gold 65Iron:Pure 17.7Cast 2-12Wrought 11.4Lead 7Manganin 3.7Mercury 1.66Molybdenum 33.2Nichrome 1.45Nickel 12-16Nickel silver 5.3(18%)Phosphor bronze 36Platinum 15Silver 106Steel 3-15Tin 13Titanium 5Tungsten 28.9Zinc 28.2


What is semi conductor diode?

Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from. Diodes used in early electronic devices were made from vacuum tubes. Somewhat later diodes were made from finned stacks of Selenium. Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.

steel wool is steel made from wool, so it would be neither

Is mercury a better conductor of heat than glass?

No, it is not. The best thermal conductor among the metals is silver, and it is the best electrical conductor as well. There is a general "rule" in the natural world that thermal and electrical conductivity are proportionate among metals; they "track" together. If a metal is a better thermal conductor than another metal, it will be a better electrical conductor as well. It should be noted that the best thermal conductor of all known materials is the allotrope of carbon we call diamond. Interestingly, diamond is an electrical insulator.


Is nickel a good thermal conductor?

Its OK: most metals are good conductors -------------------------------------------- More: since a nickel is made out of copper and nickel then it is sure to be a good conductor. ------------------------------------------------------------------------ More Information: Pure nickel is not a very good thermal conductor compared to other metals like copper. Nickel is often mixed with other metals, such as copper, and those alloys often have better thermal conductivity than pure nickel.


Is cloth a thermal conductor?

Every material substance is a thermal conductor, but not necessarily a good one. Most cloths are made of woven or knitted fibres. These are rather poor conductors, especially when made of loosely spun fibres which are then knitted rather than woven.


Is a silver bracelet a conductor or insulator?

Silver is the best conductor there is, no matter what it is made into.


Is Cool boxes an insulator or conductor?

Cold boxes are thermal insulators, however with regard to electrical conductance, that depends on what they box is made of.


Is neon the best electrical conductor?

The best electrical conductor is silver, followed by copper. Gases can be made to conduct well when they're ionized.


Is iron rod a conductor or insultator?

It is an electrical conductor, because it is made of iron. Iron, like all metals, contains "free" or "conduction" electrons which can move through the metal and carry charge. Iron is also a thermal conductor, for the same reason.


Is Water an example of thermal conductor or insulator?

It is a conductor. While air has a thermal conductivity of 0.025 W/M-K, water has 0.6 W/M-K. Air, with this thermal conductivity, is considered one of the best isolators - practically, every isolation material (for construction purposes) is made up out of little cells full with air, so most of it's volume is actually air. Water is about 24 times more conductive. Which is still pretty bad compared to the thermal conductivity of aluminum, which is 237 W/M-K.


How does cork stop the transfer of thermal energy?

Cork is made from the bark of a tree. Bark is not a good conductor. Cork also has countless pockets of dead air. Dead air space is also a poor conductor.


Why is a base of a scaucepan made of metal?

It is made of metal because metal is the best conductor of heat.
